CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority benefit of China application serial no. 201410014772.0, filed on Jan. 13, 2014. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a package structure. More particularly, the invention relates to a combined-type package structure.

2. Description of Related Art

Recently, various electronic products have been continuously launched, and thus the issue of packing said products correspondingly arises. The products need be packed so as to ensure that the products may be transported, displayed, and sold in an intact manner. Due to the long-distance delivery, if the products are not well packed or not packed in compliance with mechanics requirements (e.g., the weight-bearing requirement, the pressure resistance requirement, and so on), the contents of the package may not remain intact. Special care should be given to fragile electronic products to prevent damages caused by external forces while the products are being stored in a warehouse, transported, purchased by a customer, and delivered to the customer.

At present, plural cushion members are manually adhered to the inside of a package structure in order to protect the contents of the package structure. Nevertheless, the adhesion process of the cushion members is time-consuming and requires significant labor costs. Moreover, once the cushion members are adhered to the inside of the package structure, the cushion members can no longer be removed; alternatively, the package structure may be damaged and cannot be used again because of the improper removal of the cushion members. To sum up, use of the cushion members may lead to an issue of waste of resources. In another aspect, during the delivery process, moisture may enter the package structure and even infiltrate the electronic products in the package structure, thus reducing the service life of the electronic products and negatively affecting the operation of the electronic products.

SUMMARY OF THE INVENTION

The invention is directed to a package structure for effectively preventing a product in the package structure from being damaged or moistened. Besides, no adhesive tape is required for fixing the package structure; therefore, recycling and utilization rates of package materials may be significantly raised, and assembly time and costs may be reduced.

In an embodiment of the invention, a package structure for packing at least one object is provided, and the object is a cuboid. The package structure includes a first package container and a second package container. The first package container is a cuboid and has a receiving space and a plurality of side surfaces, and the side surfaces surround the receiving space.

DETAILED DESCRIPTION OF DISCLOSED EMBODIMENTS

FIG. 1 is a schematic view illustrating a first package container according to an embodiment of the invention. FIG. 2 is a cross-sectional view along an A-A′ direction in FIG. 1. FIG. 3 is a schematic view illustrating a projection of the first package container depicted in FIG. 1. With reference to FIG. 1 to FIG. 3, in the present embodiment, the first package container 100A serves to pack objects 20. The objects 20 are respectively a cuboid and are solar cells or other electronic devices, for instance. The first package container 100A is a cuboid and has a receiving space 101 and a plurality of side surfaces 101 a surrounding the receiving space 101. Here, only one of the side surfaces 101 a is depicted in the drawings. The objects 20 are located in the receiving space 101, and the side surfaces 101 a of the first package container 100A respectively expose ridge portions 21 of the objects 20 correspondingly.

In the present embodiment, the objects 20 are stacked and packaged as an object set 30 along a first axis A1, and the first axis A1 is perpendicular to a maximum surface 20 a of each of the objects 20. Particularly, the object set 30 described herein is formed by stacking a plurality of solar cell boards (i.e., the objects 20) and packing the solar cell boards with use of protection films, which should however not be construed as a limitation to the invention. The first package container 100A is made of a cushion material, e.g. expandable polyethylene (EPE), and the first package container 100A includes a first package assembly 110 and a second package assembly 120.

The first package assembly 110 is constituted by a pair of first wedge-shaped members 111 and a pair of first side boards 112, and the pair of first wedge-shaped members 111 is sandwiched between the pair of first side boards 112. Similarly, the second package assembly 120 is constituted by a pair of second wedge-shaped members 121 and a pair of second side boards 122, and the pair of second wedge-shaped members 121 is sandwiched between the pair of second side boards 122. Therefore, the object set 30 is respectively inserted into the first package assembly 110 and the second package assembly 120 in opposite directions, such that the object set 30 is located in the receiving space 101 defined by the first package assembly 110 and the second package assembly 120.

Specifically, in the first package assembly 110, a first gap 111 a exists between the pair of first wedge-shaped members 111. When the objects 20 are inserted into the first package assembly 110, the first ridge portions 21 a of the objects 20 are located at the first gap 111 a and exposed by the side surfaces 101 a of the first package container 100A. Likewise, in the second package assembly 121, a second gap 121 a exists between the pair of second wedge-shaped members 121. When the objects 20 are inserted into the second package assembly 120, the second ridge portions 21 b of the objects 20 are located at the second gap 121 a and exposed by the side surfaces 101 a of the first package container 100A. Here, the first gap 111 a and the second gap 121 a are opposite to each other (on an diagonal line of the objects 20). That is, the first package container 100A packs the objects 20 by rotating the object set 30 by an angle α. Specifically, when the first axis A1 acts as a normal to a projection plane, an orthogonal projection of the first package container 100A and an orthogonal projection of the object set 30 on the projection plane respectively have a square profile, and one of the square profiles is rotated relative to the other square profile by the angle α, such that the two square profiles are misaligned.

According to the present embodiment, the first package container 100A further has a plurality of cushion trenches 102 respectively located on the side surfaces 101 a, so as to prevent direct damages to the objects 20 due to the vibrations during delivery. In brief, the first package assembly 110 and the second package assembly 120 are bonded in a face-to-face manner, so as to fix the objects 20 therebetween. Thereby, impact that may be generated during delivery may be effectively lessened, and the four fragile corners (i.e., the ridge portions 21, the first ridge portion 21 a, and the second ridge portion 21 b) of each cuboid object 20 may be protected from directly hitting other objects in the surroundings. The maximum surface 20 a of each of the objects 20 is covered by the first and second side boards 112 and 122, so as to prevent the objects 20 from directly receiving external forces.

FIG. 4 is a schematic view illustrating a projection of the first package container depicted in FIG. 1 according to another embodiment of the invention. With reference to FIG. 4, in the first package container 100B, short side surfaces 111 b and 111 c at two sides of the first gap 111 a are between any two adjacent first wedge-shaped members 111, and orthogonal projections of the two short side surfaces 111 b and 111 c on a projection plane are short sides with different lengths. Besides, orthogonal projections of every two adjacent wedge-shaped members 111 on the projection plane are different wedge-shaped angles 111 d and 111 e located at two respective sides of the first gap 111 a. The projection plane is parallel to the maximum surface 20 a of each object 20. That is, the projection plane is parallel to the maximum surface of the first or second side board 112 or 122. In the two first wedge-shaped members 111 shown in FIG. 4, two included angles 111 m and 111 n are respectively defined by the extension lines of the long side surfaces 111 f and 111 g of each first wedge-shaped member 111 and the extension lines of the outer side surfaces 111 h and 111 j of each first wedge-shaped member 111, and the two included angles 111 m and 111 n are different from each other, which indicates that the lengths of the outer side surfaces 111 h and 111 j of the two first wedge-shaped members 111 on the projection plane are different from each other.

Similarly, said configurations also exist between every two adjacent second wedge-shaped members 121 and between two adjacent first and second wedge-shaped members 111 and 121, and thus no further explanation is provided hereinafter.

When the first axis A1 acts as a normal to the projection plane, an orthogonal projection of the first package container 100B and an orthogonal projection of the object set 30 on the projection plane respectively have a square profile, the two square profiles are interlaced, and one of the square profiles is rotated relative to the other square profile by an angle (i.e., the wedge-shaped angle 111 d or 111 e) with respect to the first axis A1. That is, the object set 30 is fixed in the first package container 100B by means of asymmetrical wedge-shaped members, and the object set 30 pushes against a long side surface 111 f of each wedge-shaped member.

FIG. 5 is a schematic view illustrating a first package container according to another embodiment of the invention. With reference to FIG. 5, the difference between the first package container 200 described in the present embodiment and the first package containers described above lies in that the first package container 200 is constituted by a side board 210 and four wedge-shaped members 220, and a receiving space 201 is defined by the side board 210 and the wedge-shaped members 220. After the objects 20 are placed in the receiving space 201, another side board 210 is detachable placed on and covers the wedge-shaped members 220, so as to achieve the same effects as accomplished in the previous embodiments.

FIG. 6 is a schematic view illustrating a second package container according to an embodiment of the invention. FIG. 7 is a schematic view illustrating the second package container depicted in FIG. 6 before the second package container is packed. FIG. 8 is a schematic view illustrating the second package container depicted in FIG. 6 after the second package container is unpacked. With reference to FIG. 6 to FIG. 8, in this embodiment, the second package container 300 has a first side 301 and a second side 302 opposite to each other. The first package container 100A and the object set 30 therein are suitable for being placed into the corresponding second package container 300 along the second axis A2 from the first side 301. Specifically, the second package container 300 is a box made of corrugated paper, and the second package container 300 has an imprint line profile 311 located at the second side 302 and a closable lid 312 located at the first side 301. The first package container 100A and the object set 30 therein are suitable for being placed in the box through the closable lid 312.

The imprint line profile 311 is adapted to be damaged by an external force, so as to form an opening 300 a at the box and form a lid 313 connected to the box. After the lid 313 is unfolded, the opening 300 a is exposed, such that the first package container 100A in the box and the objects 20 in the first package container 100A are capable of being taken out through the opening 300 a. In an embodiment not shown in the drawings, after the first package container 100A and the objects 20 in the first package container 100A are taken out through the opening 300 a, the first package container 100A and the objects 20 therein may be recycled and stored in the second package container 300 through the opening 300 a.

FIG. 9 is a schematic view illustrating a second package container according to another embodiment of the invention. The location of the closable lid is not limited in the present embodiment; in other feasible embodiments as exemplarily shown in FIG. 9, the difference between the second package container 300′ shown in FIG. 9 and the second package container 300 shown in FIG. 7 lies in that the closable lid 312 a is located at the second side 302 of the second package container 300′, such that the object set 30 may be placed into the second package container 300 through the closable lid 312 a. Namely, the sender is able to store the first package container 100A and the object set 30 therein by means of the closable lid 312 a, and the recipient may press (and damage) the imprint line profile 311 to remove the first package container 100A and the object set 30 therein through the opening (similar to the opening 300 a shown in FIG. 8).

FIG. 10 is an exploded view illustrating a package structure according to an embodiment of the invention. FIG. 11 is an assembly view illustrating the package structure depicted in FIG. 10. With reference to FIG. 10 and FIG. 11, in the present embodiment, the package structure 50 includes the first package container 100A, the second package container 300, and the third package container 400, and the first package container 100A and the object set 30 therein are placed in the second package container 300. The third package container 400 has a first component 410 and a second component 420 that are detachable, and the first component 410 and the second component 420 are boxes with the same profile. One of the first component 410 and the second component 420 has a first locking tab 411, and the other one has a locking hole 421. In the present embodiment, the first locking tab 411 is located on a side surface 410 a of the first component 410, and the locking hole 421 is located on a side surface 420 a of the second component 420, which should however not be construed as a limitation to the invention.

In particular, the second package container 300 is held by one of the first component 410 and the second component 420 along the second axis A2 of the package structure 50. The other one of the first component 410 and the second component 420 is assembled to the one of the first component 410 and the second component 420 along the second axis A2, and the first and second components 410 and 420 are fixed by locking the first locking tab 411 into the locking hole 421. Thereby, the first package container 100A in the corresponding second package container 300, the object set 30 in the first package container 100A, and the second package container 300 are placed in the receiving space 400 a defined by the first component 410 and the second component 420. To be specific, the second package container 300 in the present embodiment is held by the first component 410 along the second axis A2, and the second component 420 is assembled to the first component 410 along the second axis A2. However, the invention is not limited thereto.

With reference to FIG. 6 and FIG. 10, a dimension D1 of the second package container 300 along the second axis A2 is greater than an inner dimension D2 of the first component 410 along the second axis A2 and is also greater than an inner dimension D3 of the second component 420 along the second axis A2. Particularly, the dimension D1 of the second package container 300 along the second axis A2 is the sum of the inner dimension D2 of the first component 410 along the second axis A2 and the inner dimension D3 of the second component 420 along the second axis A2. The locked first and second components 410 and 420 may encapsulate the second package container 300, the first package container 100A in the corresponding second package container 300, and the object set 30 in the first package container 100A, as shown in FIG. 10.

FIG. 12 is an exploded view illustrating the first component depicted in FIG. 10. FIG. 13 is a schematic assembly view illustrating the first component depicted in FIG. 12. With reference to FIG. 12 and FIG. 13, in the present embodiment, the first component 410 includes a structural member 412 and a cover member 413. The structural member 412 is made of a cushion material, e.g., EPE, and the cover member 413 is made of corrugated paper, for instance. The structural member 412 has a first bottom plate 412 a and a plurality of first side boards 412 b, and the first side boards 412 b are vertically arranged on the first bottom plate 412 a and surround the first bottom plate 412 a. The cover member 413 has a second bottom plate 413 a and a plurality of second side boards 413 b extending from the second bottom plate 413 a, and the second side boards 413 b are bendable with respect to the second bottom plate 413 a. Since the second bottom plate 413 a is placed below the first bottom plate 412 a, and the second side boards 413 b are turned over and clamp the corresponding first side boards 412 b, the cover member 413 covers a bottom of the structural member 412 and each first side board 412 b, so as to expose the first bottom plate 412 a.

Each of the second side boards 413 b has a bendable first portion 413 b 1, a bendable second portion 413 b 2, a bendable connection portion 413 b 3, and a plurality of bendable second locking tabs 413 b 4. The first portion 413 b 1 extends from the second bottom plate 413 a, the connection portion 413 b 3 is connected between the first portion 413 b 1 and the second portion 413 b 2, the second locking tabs 413 b 4 extend from the second portion 413 b 2, and the first bottom plate 412 a has a plurality of card slots 412 a 1 adjacent to the first side boards 412 b. After the first portion 413 b 1, the connection portion 413 b 3, and the second portion 413 b 2 cover the corresponding first side boards 412 b, the first portion 413 b 1, the connection portion 413 b 3, and the second portion 413 b 2 are fixed to the structural member 412 by locking the second locking tabs 413 b 4 to the card slots 412 a 1, such that the structural member 412 is not apt to be moved.

In particular, a gap 412 b 1 exists between every two of the first side boards 412 b, and the second portions 413 b 2 of the second side boards 413 b are embedded into the gaps 412 b 1, such that the second locking tabs 413 b 4 of the second side boards 413 b are locked to the card slots 412 a 1 of the first bottom plate 412 a. Thereby, the structural member 412 and the cover member 413 can be bonded to a great extent. The first bottom plate 412 a has a plurality of cushion slots 412 a 2 located between/among the card slots 412 a 1, and the first locking tab 411 is located on an outer side of the first portion 413 b 1. After assembly, the structural member 412 and the cover member 413 are shown in FIG. 13, and the first bottom plate 412 a is exposed by the c over member 413.

FIG. 14 is an exploded view illustrating the second component depicted in FIG. 10. FIG. 15 is a schematic assembly view illustrating the second component depicted in FIG. 14. With reference to FIG. 14 and FIG. 15, in the present embodiment, the second component 420 also includes the structural member 422 and the cover member 423, and the difference between the second component 420 and the first component 410 lies in that the second side boards 432 b of the structural member 422 have a plurality of locking holes 421 located at the first portions 423 b 1 for locking the first locking tab 411.

FIG. 16 is a schematic view illustrating spacers depicted in FIG. 10. FIG. 17 is a side view illustrating spacers depicted in FIG. 16. With reference to FIG. 10, FIG. 16, and FIG. 17, in the present embodiment, the package structure 50 further includes a plurality of spacers 500. The spacers 500 are arranged in the first component 410 or the second component 420, and the spacers 500 and the second package containers 300 are arranged in the same direction. Each of the spacers 500 is located between the second package containers 300, between the second package containers 300 and the first component 410, or between the second package containers 300 and the second component 420.

Specifically, each spacer 500 includes a partition plate 520 and a cover plate 510. The cover plate 510 has a U-shaped structure to clamp the partition plate 520. The cover plate 510 is made of corrugated paper, for instance; the partition plate 520 is made of EPE, for instance. The cover plate 510 has a plurality of openings 511, and the partition plate 520 has a plurality of openings 521, and the openings 511 and 521 communicate with one another.

In the present embodiment, the cover plate 520 further has a plurality of third locking tabs 512 located at two opposite ends of a bottom of the U-shaped structure, and the partition plate 500 is vertically arranged on the first bottom plate 412 a by locking the third locking tabs 512 to the card slots 412 a 1 of the first bottom plate 412 a. Different from the card slots 412 a 1, the cushion slots 412 a 2 of the first bottom plate 412 a do not serve to fix the spacers 500 to certain locations; instead, the cushion slots 412 a 2 are expansion slots reserved for preventing the structural member 412 made of EPE from absorbing moisture and thus expanding and deforming. Thanks to the cushion slots 412 a 2, the contents of the package structure may be protected from being overly pressed and structurally damaged. Besides, the package structure is further equipped with vent holes. By placing desiccant agents (not shown) in the openings 511 and 521, the package structure and the objects therein may stay dry and will not be ruined by moisture.

To sum up, the package structure described herein includes a plurality of first package containers, a plurality of second package containers, and a third packing container. The first package containers are made of the cushion material, such that the objects in the first package containers may be protected. Besides, the first package containers and the objects therein are suitable for being placed into the second package containers. The second package containers are then held by one of the first component and the second component of the third package container, and the other one of the first and second components is locked and assembled to the one of the first and second components.

That is, no adhesive tape is required for adhering the package structure described herein, and thus the assembly time may be significantly reduced. Moreover, the objects placed in the package structure may be protected well. Since the package structure may be re-used again and again, the issue of waste of resources may be resolved. From another perspective, the package structure is further equipped with vent holes. By placing desiccant agents in the vent holes, the package structure and the objects therein may stay dry and will not be ruined by moisture.

It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the invention without departing from the scope or spirit of the invention.
